The light bar was easy to install and get wired up. However if you are not familiar with auxiliary vehicle light wiring you might have a little trouble. There was not a wiring diagram included. A simple google search can help you out. You'll need your own switch, wires, and relay. Recommend purchasing the wiring harness if you dont already have one.
The light bar could be a little brighter, but it works great for what I need. If you need long distance lighting you will need to purchase spotlights instead. This is true with all light bar applications due to the bars not set up for focal point lighting. Light bars are wide range lighting. Also, I would suggest you mount your light bar on the bumper of your vehicle instead of the roof. Roof mounting results in the light projecting so much light onto the hood which can blind you out.
As for the construction of this light, it is extremely strong and durable. Very good materials for the price. For example, I was involved in a front end collision a couple months after I mounted the light bar and the light bar took the brunt of the impact. The bull bar it was mounted on was completely flattened and the bumper was bent beyond repair. But to my surprise the light bar was bearly damaged (if you would even call it damaged). Other than some paint transferred from the other vehicle and a slightly bent heat fin on the back, it was completely unharmed. All lights work perfectly like it was fresh out of the box. Also got a fancy new bumper to mount the light bar back on.
Excellant construction and materials used.
